2 Basic safety notes
2.1 Intended use
The product was designed to grip and to temporarily and securely
hold workpieces and objects.
The product is intended for installation in a machine/system. The
requirements of the applicable guidelines must be observed and
complied with.
The product may be used only in the context of its defined
application parameters ( 6, Page 13).
The product is designed for industrial use.
To use this unit as intended, it is also essential to observe the
technical data and installation and operation notes in this manual
and to comply with the maintenance intervals.
2.2 Not intended use

7.3 Sensors
The module is prepared for a number of sensors. Other sensors
can be used with a mounting kit.
• If you require further information on sensor operation, contact
your SCHUNK contact person or download information from
our homepage.
• Technical data for the sensors can be found in the data sheets
(included in the scope of delivery).
7.3.1 Inductive proximity switch IN 80
Fig. 10 Connection example for IN 80
1
brown
2
black
3
blue
The inductive proximity switches used are equipped with reverse
polarity protection and are short-circuit-proof.
Make sure that you handle the proximity switches properly:
• Do not pull on the cable.
• Do not allow the sensor to dangle from the cable.
• Do not overtighten the mounting screw or mounting clip.
• Please adhere to a permitted bend radius of the cable.
(☞ catalog)
• Avoid contact of the proximity switches with hard objects and
with chemicals, in particular nitric acid, chromic acid and
sulphuric acid.
03.02|PGH 30-70|en
21
Assembly
The inductive proximity switches are electronic components,
which can react sensitively to high-frequency interference or
electromagnetic fields.
• Check to make sure that the cable is fastened and installed
correctly. Provide for sufficient clearance to sources of
high-frequency interference and their supply cables.
• Parallel switching of several sensor outputs of the same type
(npn, pnp) is permissible, but does not increase the permissible
load current.
• Note that the leakage current of the individual sensors
(ca. 2 mA) is cumulative.
Mounting and adjusting proximity switches for PGH 30 and 40
1 Remove spigot nut from the housings.
2 Insert proximity switches (M 8 x 1 x 32, closer) into the
housings.
3 Screw spigot nuts on the housings.
4 Connect proximity switches.
5 Test their function by closing and opening the gripper.

Troubleshooting
9 Troubleshooting
9.1 Claw jaws not moving or gripping force decreasing?
Possible cause
Corrective action
Pressure drops below minimum.
Check the air supply. ( 7.2, Page 18)
Compressed air lines switched
Check compressed air lines.
Proximity switch defective or set incorrect.
Repair the proximity switch.
Unused air connections not closed.
Close the unused air connections.
Flow control valve closed.
Open the flow control valve.
Component is broken, e.g. through
overloading
Replace component or send the module
with a repair order to SCHUNK. Ensure that
the module was only used within its defined
application parameters.
9.2 Claw jaws moving with a jerk?
Possible cause
Corrective action
Too little grease in the mechanical guiding
areas of the module
Clean the module and relubricate it.
( 10, Page 29)
Compressed air lines are blocked
Check the compressed air lines for crushing
or damage. ( 7.2, Page 18)
Mounting surface is not even enough
Check the levelness of the bolting surface.
Flow control valve is missing or not set
correctly
Install and adjust flow control valve.
